Sample Probe Problems with the sample probe can lead to fluid leaks and
pressurization problems, as well as inhibit sample acquisition.
Symptom Possible problem Solution
Sample probe leaks. The sample probe is clogged. Clean the sample probe. See
page 20.
Sample arm is stuck in the up
position.
The system isn’t properly
pressurized.
Check pressure settings. Ensure
that the sample probe is not
clogged and there are no leaks
in the syringe seal or syringe
valve.

before continuing with the
rest of the samples.
3. If the sample arm does not
raise, save the data that has
been collected. Turn off the
analyzer, but keep the XYP
instrument on.
4. Exit the Luminex software.
5. Turn the analyzer back on
and restart the software.
6. Run a Wash with distilled
water to remove air from
the system.
